DESCRIPTION OF THE PREFERRED EMBODIMENT

Body warming apparatus, generally designated 10 and constructed according to the present invention, is particularly adapted for use with a tree blind or stand, generally designated 12 that may be mounted on a tree for use by hunters, bird watchers, and others. The tree stand 12 typically includes a platform 14 having a perimetrically inverted extending angle bracket frame 16, defining an opening 17 spanned by perforated paneling such as expanded metal, a grid, or a mesh screen 20 defining a plurality of interstices or openings 22. The platform frame 16 includes front and rear frame bars 18 and 19, respectively, spanned by a pair of parallel side frame bars 21. A pair of reinforcing bars 23 also spans the side bars 21 and underlie the mesh screen 20. The mesh screen 20 may be welded or otherwise suitably fixed to the angle bracket frame 16.

A pair of curved tree engaging brackets 26 project horizontally rearwardly from the rear frame bar 19 and include oppositely extending terminal ends 28 which bear against a tree on which the tree blind 12 is to be mounted. An upstanding frame back, generally designated 32, is pivotally coupled to the rear of the platform 14 and projects upwardly to a level above the curved bars 26. The frame back 32 pivotally mounts, via hinges 33, a seat 34 which can swing from an inoperative raised position, illustrated in solid lines in FIG. 1 to a horizontal seating position, illustrated in FIG. 2. A chain or cable 35 (FIG. 8) is detachably coupled to the upper portion of the frame back 32 for surrounding a tree trunk to secure the tree blind.

The platform frame 14 and the seat 34, which are pivotally coupled to the back 32 can be folded when not in use for easy transport and storage. A pair of laterally spaced apart flaccid support cables 36 span upper portions of the back 32 and front portions of the side rails 21 of the chair frame 16. Another pair of similar flaccid cables 37 span the top portion of back 32 and the seat 34.

The warming apparatus 10 is provided for heating a person P positioned on the platform 14 and includes a heater, generally designated 40, which is disposed on the underside of the platform 16 and an insulated upwardly opening bag, blanket or robe, generally designated 42, (FIGS. 2 and 8) mounted atop the platform 14. The heater 40 includes a one-piece housing 43 comprising a flat plate or pan 44 having a centrally disposed, integral heating pot 46 provided with an upstanding side wall 48, defining an upwardly opening opening 51 having a diameter d, formed integrally with the plate 44. A bottom wall 50 spans the lower end of the side wall 48 and includes an aperture 52. The plate 44 has a breadth 45 substantially less than the breadth 47 of the platform 14.

A heat source 54, such as a commercially available propane burning heater head typically provided with commercially available Coleman® heaters, is disposed in the heating pot 46 and is coupled to a suitable source of fuel, such as a tank 58 of propane, via a fuel line 56 which passes through the aperture 52 in the bottom wall 50. A one pound propane fuel tank or other source of fuel, generally designated 58, may be stowed on a rear upwardly opening saddle or trough 60 supported by the tree engaging curved frame bars 26, as illustrated in FIG. 2. The hole 52 also allows ambient air to upwardly pass to the heater head 54 to provide sufficient oxygen to maintain a burning flame in the heating pot 46.

The heating pan 44 and integral heating pot 46 are cantileverly vertically supported on the front frame bar 17 via an integral, U or C-shaped bracket or clip 62, having a base 64 mounting a lower leg 66 integrally formed with the plate 44 and an upper leg 68 which is disposed above the platform 14 as illustrated in FIG. 2. To guard against inadvertent horizontal shifting of the heater plate 40, the rear portion of the plate 40 may be detachably secured to the platform 14 via fasteners 70 which extend through aligned apertures 72 in the plate 44 and the rear cross bars 23.

The body warming bag, generally designated 42 is provided for enveloping a person P positioned atop the grid 20. The body warming bag 42 includes a base 74 and a blanket, robe, or insulated flaccid side wall 76 having a lower end 78, coupled to the base 74, and an upwardly opening upper end 80 defining an opening 82 through which the user may enter the bag and stand on the base 74. The flaccid sidewall 76 will normally be disposed in a collapsed condition alongside the base 74 but can be vertically extended to a raised position illustrated in FIGS. 2 and 8 enveloping the user P. Suspenders, or other supports 84, may be coupled to the upper end 80 for supporting the bag sidewall 76 in the extended or raised position on the shoulders of a person P positioned on the platform 14.

The base 74 includes a central, heat ingress aperture 86 having a diameter D slightly greater than the diameter d of the heating pot 46, vertically aligned with the underlying heating pot 46 so that the heat emanating from the heat source 54 will pass upwardly, in the direction of the arrow X, through the grid openings 22 and the aligned aperture 86 into the cavity 88 in which the person is positioned.

The Operation

An individual wanting to utilize warming apparatus 10, constructed according to the present invention, will mount the heater head 54 in the heating pot 46. The user initially positions the heater 40 forwardly of the platform 14, as illustrated in FIG. 6, and then rearwardly slides the heater 40 to the cantileverly supported position, illustrated in FIGS. 2 and 7, in which the U-shaped clamp 62 vertically cantileverly supports the pot 46 beneath the central area of the grid 20. The user will then couple the burner 54 to a fuel source 58 via a fuel line 56. The user will then dispose the body bag in a collapsed condition with the bottom wall 74 of the insulated body bag 42 on the platform 14 and the opening or aperture 86 therein vertically aligned with the underlying heating pot 46. The user will then mount the tree stand 12 to a tree with cable 35 and tree mounted pegs or a ladder (not shown). The user will then position himself above the platform 14 and then step through the upper opening bag 80 onto the top side 90 of the base 74. The user may then upwardly extend the blanket side wall 76 to a position in which the suspenders 84 can be disposed over the user's shoulders to support the body bag in the elevated position, illustrated in FIG. 8.

It should be noted that the seat 34 in the horizontal position illustrated in FIG. 2 is disposed above the portion 92 of the frame mesh 20 disposed between the burner pot 46 and the rear frame bar 19. The heat generated by the heater head 54 will naturally escape upwardly through the expanded metal or mesh screen 20 in a direction of the arrow X to a position inside the body bag 42 to warm the person therein.

ALTERNATE EMBODIMENT

A slightly modified body warming apparatus 10A is illustrated in FIGS. 9 and 10 and generally similar parts are identified by generally similar reference characters followed by the subscript A.

The warming apparatus 10A includes an air impervious drape or sheet S which may suitably comprise nylon or polyester. The sheet or drape S has one end 85 stitched or otherwise suitably coupled to a lower edge portion 87 of a portion of the flaccid sidewall 76A along the front side of the platform 14A. The sheet S includes an opposite free terminal end 88 and an intermediate sheet portion 89 disposed between the ends 85 and 88 which underlies the platform 14A and the healing pan 44A. As illustrated in FIG. 10, the sheet S spans the side rails 21A and 22A to inhibit ambient air from passing upwardly thru the orifices 20A not aligned with the heating pan 44A.

The breadth 91 of the sheet or drape S is substantially greater than the breadth 45 of the heating pan 44A.

The sheet S is detachably coupled to the tree mounting brackets 26A via one or more string ties T coupled to the free terminal end 88.
